Paycheck Calculator

Your paycheck shows both your gross earnings and the various deductions that result in your net (take-home) pay. Understanding each component helps you maximize your earnings and plan your budget effectively.

Key paycheck components:

• Gross pay: Total earnings before any deductions
• Net pay: What you actually receive (take-home)
• Tax withholdings: Federal, state, and local taxes
• FICA taxes: Social Security and Medicare
• Voluntary deductions: Benefits you elect

The difference between gross and net pay often surprises people - deductions can take 25-40% of gross pay depending on income level and benefits selected.

The basic formula for calculating your net pay:

Federal Income Tax:

• Based on your W-4 form selections
• Progressive tax brackets (10% to 37%)
• Depends on filing status and allowances
• Adjust W-4 if refunds are too large or you owe

State Income Tax:

• Varies by state (0% to 13%+)
• 9 states have no income tax (TX, FL, WA, etc.)
• Some states have flat rates, others progressive
• Local taxes apply in some cities (NYC, Philadelphia)

FICA Taxes (Federal Insurance Contributions Act):

• Social Security: 6.2% on wages up to $168,600 (2024)
• Medicare: 1.45% on all wages
• Additional Medicare: 0.9% on wages over $200,000
• Total FICA: 7.65% (employee portion)

Self-employment note: Self-employed individuals pay both employee and employer portions of FICA (15.3% total).

Retirement contributions:

• Traditional 401(k): Up to $23,000/year (2024)
• Catch-up contributions: Additional $7,500 if 50+
• Traditional 403(b) and 457 plans
• Reduces taxable income dollar-for-dollar

Health insurance premiums:

• Medical, dental, vision insurance
• Often significant - $200-800/month for families
• Pre-tax reduces taxable income

Tax-advantaged accounts:

• HSA (Health Savings Account): Up to $4,150/$8,300 (2024)
• FSA (Flexible Spending Account): Up to $3,200 (2024)
• Dependent Care FSA: Up to $5,000
• Commuter benefits: Up to $315/month (2024)

Pre-tax deductions are powerful - every dollar contributed saves you your marginal tax rate.

Our paycheck calculator estimates your take-home pay:

1. Enter Income Details:
   • Annual salary or hourly rate
   • Pay frequency (weekly, biweekly, monthly)
   • Hours worked (if hourly)
2. Enter Tax Information:
   • Federal filing status
   • State of residence
   • Local tax rate (if applicable)
3. Add Deductions:
   • 401(k) contribution percentage
   • Health insurance premiums
   • HSA/FSA contributions
   • Other pre-tax benefits

Results show:

• Gross and net pay per period
• Breakdown of all deductions
• Annual totals
• Effective tax rate

Optimize your W-4:

• Don't give the government an interest-free loan (big refunds)
• Adjust withholdings if consistently getting large refunds
• Update after life changes (marriage, children, home purchase)
• Use the IRS Tax Withholding Estimator tool

Maximize pre-tax benefits:

• Contribute to 401(k) at least to get full employer match
• Use HSA if eligible (triple tax advantage)
• FSA for predictable medical/dependent expenses
• Commuter benefits if you pay for parking/transit

Understand the tradeoffs:

• More 401(k) = less take-home now, more retirement later
• Higher deductible health plan + HSA may save overall
• Don't over-contribute to use-it-or-lose-it FSA

Consider state tax impact:

• No income tax states: TX, FL, WA, NV, SD, WY, AK, TN, NH
• Remote workers may have flexibility
• Consider tax implications when relocating
